SPECIFICATION forming partl of Letters Patent No. 243,730, dated July 5,'1881.

I Application filed March 21, 1881. Y (No model.)

To all whom it may concern Be it known that I, Go'rTLIEB SGHREYER, 0fColumbus, in the county of Franklin and State of Ohio, have invented anew and useful Improvem entinVehicle-Axles; and Ido hereby declare thefollowing to be a full, clear, and exact description thereof.

It is my experience that for easy running and general ntility'it isdesirable to have a large spindle for the axles of wagons and similarvehicles. A wooden axle is preferable to a metallic one, because itunites the requisite size with lightness 5 but it has the objection thatgreat bulk is necessary to obtain the proper strength, and also that itis liable to decay. Where metallic axles and spindles have heretoforebeen combined, the construction has been such that while adapted for usewith light vehicles having small spindles,

it was not applicable to vehicles of the classto which this inventionmore particularly pertains-viz., those having large spindles-for thereason that the increased weight and the liability ofthe spindlebecoming heated were objectionable features.

The object of the present invention is to provide light and strong axlesfor heavy vehicles; and to this end it consists, mainly, in combining ahollow or tubular spindle with a webbed or anged metallic axle, wherebylightness and strength are obtained, and the overheating of the spindleis prevented by the circulation of the air within the same.

1t also consists in forming the webbed or Vflanged axle with twistedextremities, so as to bring theranges into such position at the" middleof the axle as to secure the greatest stifnessvand'strngth, and intosuch position at the extremities as will not obstruct the passage of alinchpin when the same is used.

To enable others skilled in the art to make and use my invention, I willnow describe its construction by reference to the accompanying drawings,in which- Figure l is a perspective view of one end of my improved axle.Fig. 2 is a longitudinal section of the same. Figs. 3 and 4 are cross`sections at a: x and a w. Figs. 5, 6, and 7 are crossisections of modiedforms of the flanged or webbed axle, and Fig. Sis aview showing the l tothe extremity of the axle when a linchpin is used.

I make my axle a of flange-iron, the form shown in Fig. 1 being of starshape, having two flat bars, b'b, crossing each other at right angles.The ilanges cm'ay be ot'A any desired height. The spindles are formed bycutting off the han ges c in tapering form and placing upon them atapering metallic tube, d, having a collar or shoulder, c, at the innerend. At the outer ends the axle, if anut is to be used, is made of solidcylindrical form and threaded, as at f, for the reception ofthe nut. Thecylin-` drical part f is formed-by filling up the corners j" by suitablelling-piecesI of metal, which are welded to the anges c. Where a pin isused instead of a nut the axle is given an eighth turn to bring thecorner or cavity f uppermost, and the pin-hole drilled through thecenter web, h, as shown in Fig. 8. In this case the end of the axle isnot solid, but is left of the form of the axle, and in either case thespace between the webs and inner wall of the tubular spindle ispreferably left open, to permit the unobstructed entrance andcirculation of air, though a filling of woodwould not be materiallyobjectionable, as it is not calculated to retain the heat as a solidmetal spindle or :filling wouldl do. p

The spindle d may be put on in various waystwist which is given `forinstance, it may be welded 011 and the collar e shrunk on over it, or itmay be cast with the collare on a chill, the corners f being filled withsuitable removable cores to preserve the tubular form of the spindle, asis well understood in the artof casting, or it maybe shrunk on. It isimmaterial how the spindle is put on, so long as it is done properly.

The-axle a ismade of iron, Bessemer steel,

.or other suitable metal, and may be made by rolling, after which theanges c arecut off tapering at the ends. The anges c are made of theproper height to give the desired size of spindle.

My improved axle is not only very strong, but also light enough forpractical purposes. Other form s--such as T, channel, and bayonet shapeiron, Figs. 5, 6, and 7, and other shapes of iiange-iron-may be used;but I prefer the star form described. My improved axle is IGC) cheap,light, strong, and has a large spindle. pin, in combination with atubular spindle, lo What I claim as my invention7 and desiresubstantially as and for the purpose speciiied. to secure by LettersPatent, isln testimony whereof I have hereunto set my l.
